This thesis suggests fixed quantity model and detailed performance procedures of an information system audit. In addition, an identification of the check-items with high operating risk and factors that might lead to serious effects on the business are made. Then, this thesis proposes the information system audit model that can grant priorities. By using this model, the orderer can evaluate objectively with digitized mark. The model can improve the effectiveness, reliability, and objectivity of the audit by minimizing the discrepancies of different opinions about audit evaluation results between auditee and the orderer. The proposed model is adapted to an application system and audit projects of the database construction. As a result, the model has received an equal mark from the result of the general reviews, thus the propriety of the proposed model was verified.

감리는 정보시스템의 품질을 향상시키기 위한 일련의 활동들 중 하나로 독립된 제3자가 정보시스템 구축 및 운영에 관련된 각종 위험 및 통제 상태를 점검하고 평가하여 개선이 필요한 사항을 권고하는 것이다. 그러나, 대부분의 평가가 감리인의 전문적 경험 및 주관적 판단에 의존한 정성적 방법으로 수행되고 있어 중요한 위험을 간과할 문제점을 내포하고 있다. 이에 따라, 본 논문에서는 다양한 비정형 산출물을 DTD와 스키마를 포함한 XML메타 모델인 표준포맷을 생성 후 단계별 필 통합적 방법으로 의미분석을 실시하여 자동으로 위험요소를 식별하고 평가할 수 있는 위험평가 프레임워크, 위험평가 모델, 위험평가 기준을 제안한다. 이와 같은 시스템화된 감리품질 개선기법을 통하여 추출된 결과는 감리인에게 사전에 전달됨으로써 감리노력과 일정을 절약할 수 있어 효율적인 감리수행 및 효과적인 감리결과가 보장된다.

The purpose of this study is to maximize project efficiencies in construction management by analyzing hierarchical factors that effect in project supervision system, and consequently constructing managerial CSF(Critical Success Factors). For this study, the tools for evaluating operating and management abilities of site engineers are built from analyzing status and issues, deducing influence factors and rating cardinal scales of these factors from survey results. These evaluation tools are reflected to the construction supervision decision making process so that can improve project management effectiveness.

인터넷 기술을 기반으로 하는 웹기반 시스템은 웹 브라우저를 이용한 편리한 사용성과 하이퍼링크를 이용한 효과적인 연결성을 TCP/IP 네트워크 위에서 경제적으로 제공함으로서 최근 급속히 개발이 증가하고 있다. 그러나 운영환경에서 서버 측의 다양한 플랫폼과 운영체제, 그리고 클라이언트 측의 다양한 웹 브라우저가 혼재되어 존재하는 웹기반 정보시스템의 특성은 정보시스템의 개발 뿐 만 아니라 감리에서도 기존의 메인프레임 및 클라이언트/서버 시스템의 경우와 다른 특성을 갖는다. 본 논문에서는 웹기반 정보시스템의 특성과 보안감리 규격인 SSE-CMM의 프로세스 모델에 대하여 분석한 후 웹기반 정보시스템의 보안감리를 위한 새로운 프로세스 모델에 대하여 논하였다.

In order to perform a successful outsourcing, we needs the SLA through improving the quality of IT services. In particular SLA metrics and evaluation criteria is an important factor as to substitute the IT viability of the company to promote IT Outsourcing. SLA metrics consist of technical, managerial, user perspective items, and has been managed to aim to provide reliable and continuous quality improvement of IT services. This study focuses on the HW availability metrics of SLA indicators of IT outsourcing. We propose the Infra availability criteria for the HW configuration level to meet the SLA contract and evaluation. We offer the Infra configuration standards of SLA contract, and propose criteria to determine the suitability of the target levels in IT operations audit environment. The proposed model was verified the necessity and effectiveness of the Infra configuration standards and operation audit check items through the surveys of experts and users.

네트워크를 통해 어플리케이션을 임대해주는 정보시스템 서비스 모델인 ASP 모델이 IT 시장에서 새로운 비즈니스 모델로 등장하였다. 그러나 ASP 모델은 기존의 정보시스템 모델에 비해 특정 서비스에 많은 서비스제공자가 임시적으로 결합되고, 정보자산이 공중망과 데이터센터에 위치하는 특징을 가지고 있다. 그러므로 ASP 서비스를 성공적인 수행하기 위해서는 ASP 사업자가 서비스의 제공능력이 있는지에 대한 인증활동과 ASP 서비스 도입 및 운영과정이 적절하게 이루어지고 있는가에 대한 감리활동이 요구된다. 따라서 본 연구는 ASP의 특징을 분석하고, ASP 인증ㆍ감리 프레임워크를 설계를 수행하고자 한다. 이를 위해, 기존연구를 바탕으로, 분류기준을 기술적 계층, 수명주기, 공급자/고객의 관점이라는 세 가지 차원에서 정의하며, 각각의 세부항목 및 내용을 정의하고자 한다.

Information system audit, by checking overall matters about constructing and managing information system, has to contribute to improvement of information system's quality and improving performance of projects. For this, an auditor has to present objective corroborative facts which back up result of audit and ways of improvement, but in reality, general(especially businessmen's) cognition is that audit is biased by way too subjective opinions. Local experience and theoretical research until now propose that tools of automating audit will be an active means of systematically collecting and proposing these objective evidences of audit. This research not only verified that in the field of audit, phenomenon of technology application can be explained and predicted by applying TAM, but it also contributed in extending theoretical base on information technology and audit by distinguishing several characteristics which appear in the process of the model's application and analysis.

An information System Audit by the recognition of a problem and suggestions for solutions for overall matters about constructing and managing information systems is needed in order to contribute to the improvement of an information system's quality and improving the performance of projects. In reality, however, the general cognition is that audit is biased by subjective opinions. For this, an auditor needs to measure the level of recognition of the usability and convenience of the technologies of automating audit by applying TAM in the information system audit, and to analyze the relationship with recognition and availability of the interested parties for the technology (tool) of the audit. By the hypothesis verification result, an auditor needs to present objective corroborative facts that back up the level of recognition and usability for the information technology in the field of audit. This study verified that the phenomenon of technology application can be explained and predicted by applying TAM in the field of audit. Through an empirical study of the recognition level of audit and contractor, the developer suggests that the audit plan stage is similar to the audit corrective action stage, but the audit action stage is different from the audit review stage. This research can verify the audit technology preferred for the availability and intention of use and usability.

The considerable budgets for the 2nd-phase NGIS projects are allocated to the projects for developments of the GIS applications. Especially, the 78 local governments are major users of GIS application systems. In spite of GIS necessity in local government, whether a GIS is 'good' or bad, depends on its implementation and operation. How to implement GIS in effective wav and how to measure GIS effect for justifying GIS funding can be major concerns. Because it takes minimum 3-4 years to equal the costs and benefits of GIS, the long-terms implementation strategies for GIS project in local government are required. In order to establish a proper implementation model for the GIS application projects and to promote activities in the projects, this study considers several problems in accordance with the phases of GIS evolution and solutions of these problems. Based an the GIS auditing and consulting experience in local governments, this study constructs a GIS implementation and maintenance model in long and comprehensive perspective. This model can be a key to affective and realistic implementation for the future GIS projects.

Highly probable cause of the current turmoil critical national infrastructure and private enterprise information systems failures or national event of an accident, it is inevitable huge hit in corporate business as well as a significant impact on the national benefit. This is a trend subject to the stability of the national management information system has a significant impact on people and society, such as banking, telecommunications, transport and energy, which can be extended into a private institution. However, public and private ICT business through the development of Information system Audit or CMMI(Capability Maturity Model Integration) certification check the quality of the target system, but quality check on the reliability of the information system operations after construction is either not promoting met for some safety test results a situation that does not enabled by insufficient. By preventing the disorder or an accident of this study, the diagnostic reliability information systems through inspection and evaluation system development of information systems being established, and to minimize service confusion and study ways to ensure customer - oriented service.
